LEV | Heart
your heart is where you experience joy. In Hebrew, to be happy is to be “good of heart” or to have a “heart of joy.” So the heart is the generator of physical life. It’s also the center of your intellectual and emotional life. And there’s more. In biblical Hebrew, the heart is where you make choices motivated by your desires. So David had it “in his heart” to build a temple for God Your heart is where your affections are centered. They’re called “the desires of your heart.” And if you really want something and go after it, it’s like what Nathan said to David, “whatever is in your heart, go and do it.”
Then the heart is the center of all parts of human existence. As in the well-known Proverb, “guard your heart because from it flows your whole life.”
